320-70240000 - Miller Smith 320 Series High Purity Stainless Steel Regulator, CGA 580, 2-Stage, 0-25 PSI

Precision Control for High Purity Applications

The Miller Smith 320-70-24-00-00 High Purity Corrosion Resistant Stainless Steel Two Stage Regulator is an elite instrument engineered for the most demanding gas delivery systems. Designed specifically for analytical instrumentation, process control, and laboratory applications, this regulator excels in managing both corrosive and non-corrosive gases where maintaining gas stream purity is paramount. The unit features a robust 316 stainless steel bar stock body, ensuring minimal particle generation and maximum resistance to chemical attack.

Advanced Two-Stage Design

Unlike single-stage counterparts that suffer from decaying outlet pressure as the cylinder empties, this two-stage regulator provides a constant delivery pressure throughout the life of the cylinder. This is achieved by reducing the pressure in two steps, effectively isolating the final delivery pressure from the fluctuations of the high-pressure inlet. For applications requiring a steady 0-25 PSI output, such as chromatography or precise chemical reactions, this stability is critical.

Superior Leak Integrity and Safety

Safety and integrity are built into the core of the 320 Series. The regulator utilizes a metal-to-metal diaphragm seal, which provides a far superior seal compared to elastomeric options, significantly reducing the risk of gas contamination or leakage. The diaphragm itself is made of convoluted stainless steel, offering excellent sensitivity and response to pressure changes. Furthermore, the bonnet features captured vent ports (1/16" FNPT), allowing operators to pipe hazardous or toxic gases away to a safe scrubbing system in the rare event of a diaphragm failure.

Material Excellence

Every wetted component is selected for compatibility with high-purity requirements. The seat is manufactured from PCTFE, a material chosen for its hardness and chemical resistance, ensuring a tight shut-off even after repeated cycling. A 316 stainless steel filter protects the seat from particulate damage, extending the service life of the regulator. The unit is also designed to withstand internal vacuums, making it suitable for rigorous purging operations essential in ultra-high purity environments.
